So just as I expected the collective wisdom on this forum was exactly correct. When I returned to the boat today and looked into the engine compartment, I had 2 8D batteries emitting that rotten egg smell and very warm to the touch. IR temp gauge shows 133 on one and 131 on the other. Shut off the charger (an older Protech 1250) and vented the compartment.
After removing the old batteries I turned the CO monitor back on and it shows 0 PPM both in the cabin as well as in the engine compartment.
Many thanks to all who helped figure this out. Now I just have to decide what batteries to put back in and if I need to change the charger. Sounds like another boat buck is on its way out of my bank account
Oh well, part of the deal.
